I’d strongly encourage you to consider another platform like SES, SendGrid, Postmark, etc.

I would not trust or recommend MailChannels, personally. More details: workers-and-pages-discussions

Generally yes, with domain lockdown. But their response and handling of the situation was, and still to this day is, terrible, and not a company I can recommend using for any use case unfortunately.

Has anyone used lerna? I was wondering what was the best way to share code between workers. For example custom auth handling functions ?

K

kian•11/15/23, 10:47 AM

The Workers 'native' way would be having a Worker dedicated to auth that the rest of your Workers can call via https://developers.cloudflare.com/workers/configuration/bindings/about-service-bindings/, but that does incur another request charge.

S

Stone•11/15/23, 11:04 AM

Interesting.. but could it be done differently? Using lerna and have a common code module? I'm a bit old school

K

kian•11/15/23, 11:05 AM

Sure, but that's not Workers specific.

K

kian•11/15/23, 11:06 AM

Wrangler just uses esbuild and bundles your Worker - use NPM packages, import from a file path, etc

For the async part, https://developers.cloudflare.com/workers/runtime-apis/handlers/fetch/#contextwaituntil.

This gives you 30 seconds after returning the response where your Worker will continue running.

Yes

Just pass it a function that returns a Promise, without awaiting it

i.e

ctx.waitUntil(foo())

ctx.waitUntil(foo())

ctx.waitUntil(foo())

ctx.waitUntil(foo()) not

ctx.waitUntil(await foo())

ctx.waitUntil(await foo())

ctx.waitUntil(await foo())

ctx.waitUntil(await foo())

async function doStuff() {
  await scheduler.wait(1000);

export default {

    ctx.waitUntil(doStuff());

  }
}

async function doStuff() {

Yes, I came across that one. But I kept coming up with d1, r2, and cloudflare ai. But euh yes again I did not fully read the docs. Sorry

K

kian•11/15/23, 1:26 PM

Because then you're waiting for the Promise to resolve before it's passed to waitUntil, meaning waitUntil is useless.

K

kian•11/15/23, 1:27 PM

The idea is that

waitUntil will keep your Worker alive, after returning a

Does your Worker have Service Bindings? Canceled is typical with those if the requesting Worker doesn't read the body.

The product merge has not happneed yet so we are in the state before that where Image Resizing and Images are separate products.

In this state, an Images subscription does not impact your ability to resize. Using Image Resizing in this state requires the feature to be enabled on a Pro ($25/mo) plan zone.

Once the product merge happens, your Images subscription will begin allowing you to resize and if you are not storing images you will be able to use the $0/mo plan that will be added.

So rather than the merge causing problems, the merge will fix them when it happens

E

Erisa•11/15/23, 3:06 PM

Well you can if you want but you can also wait a short time for the product merge which will not require Pro anymore

E

Erisa•11/15/23, 3:06 PM

up to you whether thats worth it

E

Erisa•11/15/23, 3:06 PM

and depends how much of a hurry you're in

E

Erisa•11/15/23, 3:08 PM

After the merge you need a Images subscription but there will be a new $0/mo + usage tier added
